Filed: 1936-12-21
Abstract: 480,907. Prepayment mechanism for meters. PEET, A., and ALDER & MACKAY, Ltd. Dec. 21, 1936, No. 35103. Addition to 446,177. Drawings to Specification. [Class 27] The prepayment meter-operating knob described in the parent Specification is modified so that the two axially movable drive-transmitting clutch members provided therein may slip in both directions of rotation. Both faces of the interengaging clutch jaws are inclined to the axis of the knob, those operative during forward rotation to prepay at an angle, for example, of 20‹, and those operative during the return rotation at an angle, for example, of 45‹. During forward rotation, slip only occurs if the mechanism jams, as when the limit of prepayment is reached. Slip always occurs during the return rotation for the purpose explained in the parent Specification. The driving connection between the knob and its clutch member is effected by axial grooves in its inside walls which accommodate ribs on the clutch member.

Title: Audio signal quality indicating circuit
IPC: H04B7/08
Filed: 1972-07-27
Abstract: 1361124 Measuring noise GENERAL ELECTRIC CO 27 July 1972 [2 Aug 1971] 35154/72 Heading G1U [Also in Division H4] An arrangement for giving a measure of the quality of an audio-frequency signal by determining the amount of background noise is described in relation to a diversity reception system in which the best quality signal is selected for application to a common amplifier 11. Each radio receiver is provided with the selecting apparatus shown in Fig. 2, in which the audio signal from a receiver is amplified at 13 and supplied via gate 14, if the receiver is unsquelched, to the selection gate 15. Each receiver supplies an audio tone signal when it is squelched, which when detected at 22 blocks the gate 14. Signals from the gate 14 are also supplied via a logarithmic amplifier 16, in which the gain decreases as the input increases, to an envelope detector 17. A gate 18 passes the output of detector 17 to a valley detector 19, if the receiver is unsquelched. Detector 19 detects the lowest level of the envelope signals, which is a measure of the background noise, and has a relatively long time constant so that its output remains substantially constant between syllables of received speech signals. A circuit 20 passes the output of detector 19 only if the receiver is unsquelched and there is no failure in the line from the relevant receiver 25 as tested at 23. The output of detector 19 is supplied to a transistor in a selection circuit 21 which is coupled to a constant current source 10 the selection circuits of the other receivers being similarly coupled to the source 10. In operation the detector 19 providing the lowest voltage (the best signal) causes the corresponding transistor to conduct and open gate 15 and back-bias the remaining transistors in circuits 21. A latching circuit 25 ensures that when a selection is made it remains unchanged until another signal becomes approximately 10% better than the one selected.

Abstract: 969,952. Frequency converting. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 14, 1960 [Oct. 21, 1959], No. 35747/59. Heading H2F. A frequency multiplier comprising reactors having cores 6, 7 and 8 which exhibit rectangular hysteresis loops, the windings 9, 10, 11 being connected in star to an n phase supply 1, 2, 3 of frequency f, supplies a load 5 connected between the star point 15 and neutral supply line 4, with a regulated voltage of frequency nf. The reactors are designed to saturate at about 120 degrees after each supply voltage zero. The regulation is achieved by balancing, for maximum load, at point 22, a voltage of frequency nf, induced in series connected secondary windings 12, 13 and 14 of the saturable reactors, against a reference voltage of frequency nf developed by star-connected saturable reactors 19, 20, 21. When the load varies, the voltage induced in windings 12, 13, 14, varies, and the difference between this voltage and the reference voltage circulates a biasing current through the windings 12, 13, 14, which tends to restore the load voltage.

IPC: G05D1/06
Filed: 1961-10-09
Abstract: 990,243. Automatic control of aircraft. ELLIOTT BROS. (LONDON) Ltd. Nov. 14,1962 [Oct. 9,1961], No. 36235/61. Heading G3R. In a system for automatically controlling both the collective and differential thrusts of two engines or groups of engines on an aircraft,the desired thrusts are determined by electrical signals,set manually,which control the engine throttles in an appropriate manner in conjunction with signals dependent on the engine thrusts. In Fig. 1 electrical signals dependent on the thrust of port or forward jet engines 11 on a VTOL or STOL aircraft and electrical signals dependent on the thrust of starboard or after jet engines 12 are derived by meters 14, 15 and automatically corrected by variable gain devices 3 2,31, adjusted in dependence on nozzle angles, to give signals, representative of the vertical components of thrust, which are applied to amplifiers 34,33 respectively. The outputs of amplifiers 34,33 are combined in an amplifier 23 and compared with signals representing desired total thrust set by a manual lever 16 so that any deviation results in an output from amplifier 23 which, through amplifiers 28,24, energizes engine throttle actuators 29, 25 to correct the total vertical thrust. Positional feedback is applied from the throttle actuators to the inputs of amplifiers 28, 24. The signals representing the thrusts of the two sets of engines are also applied in opposite senses to an amplifier 35 which compares their difference with signals representing desired differential thrust set by a manual lever 17,a manual trim device 21,or an automatic trim device 22. The output of amplifier 35 is applied in opposite senses to amplifiers 28, 24 to vary the thrusts differentially and thus control the roll or pitch attitude of the aircraft. The total and differential thrust datums may also be controlled by an autopilot 40.

Filed: 1964-09-04
Abstract: 1,029,767. Semi-conductor devices.. LITTON INDUSTRIES Inc. Sept. 4, 1964 [Sept. 12, 1963], No. 36393/64. Heading H1K. A semi-conductor diode or transistor includes a region comprising two contiguous layers of different conductivity but the same conductivity type, one of the layers being formed by diffusion of impurity into a substrate and the other by deposition of doped semi-conductor on to the diffused substrate. A transistor of low saturation resistance but high breakdown voltage may be constructed using such a region as its collector zone, the former layer being of high conductivity and the latter, adjacent the collector-base junction, of low conductivity. The integrated circuit of Fig. 7 (not shown), consisting of a plurality of transistors on a common substrate, is produced by first forming on a silicon substrate 40, Fig. 4 (d), an oxide mask 41 through which phosphorus is diffused to provide high conductivity N-type layers 43. The oxide mask 41 is then removed by etching with mechanical vibration and a new mask 46, of oxide with a trace of an organoboron compound, is formed through which a layer 48, Fig. 4 (f), of low conductivity N-type silicon is epitaxially deposited on part of the surface of each layer 43 at a temperature sufficiently low- 1150‹ C. or less-to inhibit deposition on the oxide of mask 46. A P-type region 50 is then produced by boron diffusion through a new mask on to part of each layer 48; the treatment may be stepped at this stage if diodes rather than transistors are required. To convert these diodes to transistors a further diffusion of N-type material into the P-regions 50 is performed, resulting in the structure of Fig. 7. The connections to and between the transistors of Fig. 7 are laid down by vapour deposition of aluminium followed by photo resist etching or by thermo-compression bonding.

Filed: 1967-08-08
Abstract: 1,189,830. Supercharging I. C. engines; power plant. SULZER BROS. Ltd. Aug. 8, 1967 [Sept 9, 1966], No. 36415/67. Headings F1B and F1Q. In an I. C. engine, having an exhaust gas turbine driven supercharger unit 2, Fig.1, additional power is supplied to the supercharger unit by an auxiliary drive comprising a hydraulic positive displacement motor 11 coupled to shaft 5 direct by and without transmission gearing. Operation: Oil is supplied from tank 18 via a transfer pump 20 and a high-pressure pump 16 to a hydraulic motor 11 and is returned to tank 18 via a pressure-maintaining valve 28 which prevents foaming or cavitation. At higher engine outputs when an auxiliary drive is not required the air pressure in a reservoir 8 acts via a signal line 25 on a servomotor 24 to fully or partially open valve 23 to by-pass the motor 11. If the oil flow through motor 11 is greater than the oil flow through pump 16 the motor 11 acts as a pump drawing oil via a line 30 through a relief valve 31. Alternatively pump 16 may be arranged to continuously supply oil to the motor 11. Pump 16 may be driven from the engine crankshaft or by a separate constant or variable speed motor. Valve 28 may be omitted and pump 16 may be the same construction as pump 11. Coupling 10 may be resilient or releasable during operation e.g. an over-running clutch, an electromagnetic coupling, a friction clutch or a hydraulic coupling. In an alternative arrangement the transfer pump is the engine lubricating pump (40), Fig. 2 (not shown) and lines 30 and 17 both lead to the pressure line (42) of the lubricating pump (40).
